.norton SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	9.0ms	20ms	324
7d	100%	100%	9.0ms	64ms	1794
30d	100%	100%	9.0ms	479ms	10278

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	81.25%	100%	204ms	271ms	64
7d	83.33%	100%	206ms	262ms	348
30d	84.37%	100%	206ms	259ms	1932

DNSSEC Validation Metrics

Registry Agreement Spec 6

DNSSEC is required by the Registry Agreement (Specification 6) but is not part of the Spec 10 SLA. We monitor DNSSEC validation independently.

Period	Validation Rate	RTT p50	RTT p95	Checks
24h	100%	35ms	37ms	88
7d	100%	35ms	36ms	476
30d	100%	35ms	36ms	2672

Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
